chore(release): 0.21.6 coordinated (npm/PyPI/NuGet 0.21.6 · Maven 7.21.6)

Merges five branches: the ts-poet split-tree duplicate-import fix, four
adopter-audit blind-spot closures, the Angular source-only decision, the
cross-port `like` ruling, and referential actions on identity.reference.

TWO changes alter runtime behaviour on an existing database, and lead the
changelog rather than sitting in a list: `like` becomes case-sensitive on
Postgres (FR-009 always specified SQL LIKE; only one branch of one HTTP parser
disagreed), and the first `meta migrate` after upgrading emits a migration adding
ON DELETE actions to live foreign keys (a parent-side composition was silently
contributing nothing).

Both correct previously-wrong behaviour rather than changing a contract, which is
why this is a PATCH — the same call, on the same defect class, as the Java LIKE
fix in 0.21.4.

ADR numbering: three agents independently wrote ADR-0047. Referential actions
keeps 0047 because that string is baked into byte-gated registry attr
descriptions; the two documentation-only decisions renumbered to 0048 (Angular)
and 0049 (like).

+
+A coordinated PATCH across all four registries. **Two changes alter runtime behaviour on
+an existing database — read these two before upgrading:**
+
+1. **`like` is now case-SENSITIVE on Postgres** (it was dispatching `ILIKE`). FR-009 always
+   specified SQL `LIKE`, and TS's own persistence drivers were already case-sensitive — only
+   one branch of one HTTP parser disagreed, so a query returning extra rows today will return
+   fewer after upgrading. Case-insensitive matching stays available via `?search`; an `ilike`
+   operator remains deliberately unadded (ADR-0049).
+2. **The first `meta migrate` after upgrading emits a migration ADDING `ON DELETE` actions to
+   live foreign keys.** A parent-side `relationship.composition` was silently contributing no
+   referential action; it now contributes its subtype default. This changes production delete
+   semantics — pin `@onDelete: "no-action"` on the reference to keep current DB behaviour
+   (ADR-0047).
+
+Both are corrections of previously-wrong behaviour rather than contract changes, which is why
+this is a PATCH — the same call, on the same class of defect, as the Java `LIKE` fix in 0.21.4.
+
+
 ### Fixed — parent-side `relationship.composition` reaches the child's FK (migrate-ts; ADR-0047)
 
 > **ADOPTER-VISIBLE MIGRATION — production delete semantics change.** After
